Dmaic Carbon impregnated grade are made from fine-grained, high strength, carbon-graphite that is fully impregnated with chemically resistant resin or metal. The material is dimensionally stable so that carbon graphite product faces can be polished to one helium light band flatness, and the flatness is retained indefinitely. The material is chemically resistant to almost all liquids except extremely strong, oxidizing acids and alkalis. Carbon Graphite Bush, and Carbon Vanes machined from these blanks are impervious to high-pressure liquids.
Dmaic Carbon Products can be modified for various Impregnation such as:
| Grade | Impregnation Type | Bulk Density (g/cm³) |
Porosity % |
Hardness Rockwell D |
Compressive Strength Mpa |
Transverse Strength Mpa |
Heat Resistance (°C) |

| DC-3114 | Babbitt | 2.4 | 1 | 90 | 260 | 85 | 200 |
*Any specified grade from above can be modified according to bulk density, compressive strength and heat resistance as per requirement for batch or mass production.
All above grade are available in the bonded composite as well.
